Question

Eu preciso da resposta e os cálculos!

Answer 1

$1. \: \: \frac{mv {}^{2} }{2} = \frac{80.4 {}^{2} }{2} = \frac{80.16}{2} = \frac{1280}{2} = 640$

$2. \: \: mgh = 95.2.10 = 95.20 = 1900$

$3. \: \: \frac{kx {}^{2} }{2} = \frac{180.0,1 {}^{2} }{2} = \frac{180.0,01}{2} = \frac{1,8}{2} = 0,9$

Espero ajudar nos estudos ❤
